CVE-2026-73263 — CRITICAL (9.9)

Vulnerability Description

Prowler is a cloud security platform. Prior to 5.36.0, the Kubernetes provider connection test accepted kubeconfig_content containing a legacy gcp auth-provider with config.cmd-path and config.cmd-args because kubeconfig_contains_exec_auth in api/src/backend/api/v1/serializers.py checked only exec blocks, and POST /api/v1/providers/{id}/connection loaded it through config.load_kube_config_from_dict in prowler/providers/kubernetes/kubernetes_provider.py, causing kubernetes-python CommandTokenSource.token to run the attacker-supplied command through subprocess.Popen on the shared worker. This issue is fixed in version 5.36.0.
